3D Printing Engineer • Independence, Kentucky
About Kevin Practical 3D Printing Starts With the Problem.
I help individuals, makers, teams, educators, and small businesses turn broken parts, rough ideas, measurements, sketches, and digital models into practical 3D-printed solutions. My goal is not to make every project sound easy. It is to make the decisions clear, the expectations honest, and the finished part useful.
Who is Kevin? Kevin is a 3D printing engineer and the founder of 3D Printing by Kevin, an Independence, Kentucky-based service focused on custom FDM parts, replacement components, prototypes, design support, small production runs, and practical beginner education.
My Story
I learned to look for the failure before reaching for the tool.
Long before 3D Printing by Kevin became a business, I worked around machinery, repairs, tools, and real-world problems. My background in industrial machine repair taught me that a successful fix begins with understanding what failed, what forces are involved, and how the replacement must interact with everything around it.
I later spent more than 14 years at Xavier University. During those years, 3D printing developed from an interesting technology into a practical tool I could use to design, test, repair, organize, and improve everyday objects.
What started as hands-on experimentation became years of printing, 3D modeling, material testing, troubleshooting, scanning, and refining parts that needed to do more than look impressive in a photograph. The projects that interested me most were the useful ones: a bracket that fit, a holder that solved an awkward problem, a replacement piece that was no longer sold, or a prototype that answered an important question before someone invested more money.
That problem-solving approach still guides the business today. I do not begin by asking which printer is newest or fastest. I begin by asking what the part must accomplish.
The printer is a tool. The real work is understanding the problem, the fit, the material, and the consequences of failure.
What I Do
Practical services for parts that need to fit, function, or prove an idea.
Some clients arrive with a finished model. Others arrive with a broken piece, a photograph, a sketch, or a problem they cannot solve with an off-the-shelf product.
Replacement and Discontinued Parts
Recreate suitable plastic clips, covers, spacers, brackets, tabs, guides, and other components when the original is broken, unavailable, or impractical to replace.
Explore replacement-part work →Custom Mounts, Holders, and Organizers
Design around the actual tool, device, wall, shelf, machine, vehicle interior, or workspace instead of settling for a nearly-right product.
See custom mounts and holders →Rapid Prototypes
Test shape, fit, handling, assembly, and basic function before committing to more expensive tooling or production decisions.
Learn about prototype support →Design and Model Refinement
Move from rough geometry, measurements, sketches, scans, photographs, or incomplete files toward a model that can be evaluated and printed.
See how design supports printing →Small-Batch Functional Parts
Produce one part, several copies, pilot quantities, shop aids, replacement inventories, or early product runs when mass manufacturing would not make sense.
Discuss quantity and project fit →My Signature Framework
The P.R.I.N.T. Method
This is the practical decision process I use to keep a project focused on what the finished part must do—not merely on what a printer can produce.
Problem
Define the failure, inconvenience, missing component, or opportunity before choosing a machine or material.
Requirements
Identify load, heat, weather, flexibility, appearance, lifespan, safety, quantity, and finish needs.
Interfaces
Measure every point that fits, clips, slides, screws, supports, locates, clears, seals, or rests against another object.
Next-Best Materials & Methods
Choose the most sensible design approach, filament, printer, orientation, walls, infill, supports, and workflow.
Test & Tune
Print a controlled version, check the important dimensions and behavior, adjust deliberately, and verify the result.
Project Fit
What I am comfortable making—and what deserves a closer review.
Clear boundaries are part of responsible 3D printing. The fact that an object can be printed does not automatically mean it should be used in every application.
Often a strong fit
These projects commonly benefit from customization, low quantities, quick iteration, or unavailable replacement parts.
- Brackets, clips, spacers, covers, knobs, guides, and organizers.
- Custom mounts and holders built around a specific object or location.
- One-off parts, prototypes, test pieces, and small batches.
- Models that can be measured, photographed, recreated, or scanned.
- Projects where a physical test can answer fit or usability questions.
Needs a closer conversation
These applications may require another process, professional certification, specialized testing, or a decision not to proceed.
- Parts whose failure could injure someone or damage costly equipment.
- Safety-critical automotive, structural, lifting, or load-bearing components.
- Pressure-containing parts or items exposed to sustained extreme heat.
- Certified medical, food-contact, or regulated applications.
- Projects requiring machining-level tolerances or another manufacturing method.
How We Will Work
You do not need perfect files or technical vocabulary.
You need enough information to explain the problem, the important dimensions, the expected use, and what a successful result should accomplish.
Share the problem
Send a description, photographs, measurements, sketches, a broken original, or available STL, STEP, OBJ, 3MF, and PDF files.
Review the requirements
We consider fit, use, material, heat, stress, appearance, quantity, deadline, safety, and the information still needed.
Prepare the model and plan
The file is checked, refined, recreated, or designed, and the material and print approach are selected with purpose.
Print, inspect, and improve
The part is evaluated by whether it solves the problem. When appropriate, a test version helps confirm fit before final production.
Inside the Workshop
Different machines for different project requirements.
I work with several FDM printers because build size, enclosure, material behavior, speed, reliability, and part geometry can point toward different equipment. I do not choose a machine because it is the newest. I choose it because it is the better fit for the job.
Teaching Practical 3D Printing
I also help people understand the decisions behind better prints.
Not everyone needs someone else to print the part. Some visitors want to become more capable with their own machines. My educational content focuses on useful projects, reliable habits, material choices, troubleshooting, design thinking, and the reasons settings matter.
How I Build Trust
Clear limits, responsible tools, and no invented experience.
The same standards that guide customer projects also guide the articles, recommendations, and educational resources published on this site.
Hands-On Claims Stay Hands-On
I distinguish between equipment I personally use, products I evaluate through published information, and ideas that still require testing. I do not present research as personal experience.
AI Supports—It Does Not Replace Judgment
I may use AI to help organize ideas, compare questions, identify gaps, or improve clarity. Final recommendations, project decisions, examples, and responsibility remain mine.
Affiliate Links Do Not Decide the Answer
Some pages contain affiliate links. A product belongs in the discussion only when it fits a practical use, and readers should still compare specifications, support, cost, and project needs.

Quick Answers
Questions people often ask before reaching out.
Do I need a finished 3D model before contacting Kevin?
No. You can begin with an STL, STEP, OBJ, or 3MF file, but photographs, measurements, sketches, a PDF, a scan, a broken original, or a clear explanation of the problem can also provide a starting point.
What type of 3D printing does Kevin offer?
The current service focuses on FDM printing with filament-based materials. Resin printing is not currently offered because the workspace and safety process are being treated as requirements—not afterthoughts.
Can Kevin reproduce any broken plastic part?
No. Some parts are strong candidates, while others involve hidden geometry, unsuitable materials, extreme heat, important safety requirements, patents, or manufacturing methods better handled another way. A project review helps determine what is realistic.
Does Kevin work only with local customers?
No. Local pickup and project discussions can be convenient in Northern Kentucky and Greater Cincinnati, but remote projects may also work when the geometry, files, measurements, photographs, communication, and shipping are manageable.
Can private product ideas be discussed confidentially?
Yes. Explain through the project intake form that confidentiality matters. Private project steps and NDA handling can be discussed before sensitive files or detailed intellectual property are exchanged.
Does Kevin guarantee that the first print will be the final version?
No responsible designer should promise that for every custom part. Simple, proven files may print successfully immediately, while new functional designs often benefit from a controlled test, fit check, or revision before final production.
Can beginners learn directly from 3D Printing by Kevin?
Yes. The site includes free practical guides, troubleshooting articles, material explanations, and the P.R.I.N.T. It: Practical 3D Printing for Beginners ebook.
